It used to be that the luxury car wheat was separated from the regular car chaff by its construction — the finest materials, handmade bodies, and polished precision parts under that custom skin. But that era ended years ago, so now we have gizmos.

My current favorite is the 'atomizer fragrances' you can get in the mass-produced 2014 Sonderklasse. You get four smells that get backlit by LEDs if you check the right options box. Because the new car smell isn't for everyone, I guess.

What do you think is the most ridiculous feature you can find in a luxury car these days?
